要计算你的平均绩点，用你在某门课上获得的具体成绩，用相应的成绩点数(见下文)乘以该门课的学分数，就可以计算出总成绩点数. 重复此过程 each class; then add all grade points earned and divide by the total number of credit hours attempted. 结果应该等于你的平均绩点.
| 信等级 | 平均绩点 | 信等级 | 平均绩点 |
|---|---|---|---|
| A | = 4.00 | C | = 2.00 |
| A- | = 3.70 | C- | = 1.70 |
| B+ | = 3.30 | D+ | = 1.30 |
| B | = 3.00 | D | = 1.00 |
| B- | = 2.70 | D- | = 0.70 |
| C+ | = 2.30 | F | = 0.00 |
